- Q1El M.A.S. es provocado por la fuerza elástica. Esta fuerza es:Constante en módulo.Proporcional a la elongación y de sentido opuesto.Proporcional a la amplitudInversamente proporcional al desfase30s
- Q2¿Qué nos indica el desfase?El tiempo que tarda el cuerpo en ponerse en movimiento.La posición del cuerpo después de transcurrido un tiempo igual a un periodoLa posición del cuerpo en el instante inicialLa frecuencia del movimiento.30s
- Q3¿Cuál es la magnitud de la amplitud de un sistema de masa de resorte donde la frecuencia angular es π rad/s, y la masa se desplazamiento de 4 cm en 1 segundo? (Suponga que está comenzando a medir el tiempo (t = 0) en el desplazamiento máximo).4 cm3/4 π cm8 cm1 cm30s
- Q4Where is the net force greater in the oscillating movement of a mass tied to a spring?At the greatest compression.In the equilibrium position (center).In the greatest extent.In the greater compression and greater extension.30s
- Q5Where is the net force greater in the oscillating movement of a mass tied to a spring?In the equilibrium position (center).At the greatest compression.In the greatest extent.In the greater compression and greater extension.30s
- Q6What is simple harmonic motion? Any motion where a restoring force is applied that is proportional to the square of the displacement, in the opposite direction of that displacement.Any motion where a restoring force is applied that is inversely-proportional to the displacement, in the opposite direction of that displacement.Any motion where a restoring force is applied that is proportional to the displacement, in the same direction as that displacement.Any motion where a restoring force is applied that is proportional to the displacement, in the opposite direction of that displacement.Any motion where a restoring force is applied that is inversely-proportional to the displacement, in the same direction as that displacement.30s
- Q7At what point in a pendulum's motion is the acceleration greatest?We need more information to know.At minimum displacement (the middle).At maximum displacement (the outer edges).The acceleration is the same at all times.30s
